Rev 2 April, 2002 1 A-Data ADABC1616 PC-133 SDRAM Unbuffered DIMM 16Mx64bits SDRAM DIMM based on 8Mx8, 4Bank, 4K Refresh, 3.3V SDRAM General Description Features The ADABC1616 is 16Mx64 bits Synchronous DRAM Modules, The modules are composed of sixteen 8Mx8 bits CMOS Synchronous DRAMs in TSOP-II 400mil 54pin package and one 2Kbit EEPROM in 8pin TSSOP(TSOP) package on a 168pin glass-epoxy printed circuit board. The A-Data is a Dual In-line Memory Module and is intended for mounting onto 168-pins edge connector sockets. Fully synchronous operation referenced to the positive edge of the clock. All inputs and outputs are synchronized with the rising edge of the clock. The data paths are internally pipelined to achieve very high bandwidth. *PC-133 support *Auto refresh and self refresh *4096 refresh cycles / 64ms *Single 3.30.3V power supply *All device pins are compatible with LVTTL interface *Data mask function by DQM *Serial Presence Detect with EEPROM *Module bank : two physical bank *PCB : B6986RAB,Height (28.00mm),double sided component, Four layers Ordering Information.
